One of the enduring dogmas of global finance holds that gold is a safe-haven asset. The precious metal is billed as a hedge against inflation, the ultimate insurance policy against geopolitical risk and protection during periods of financial-market turmoil.

Investors -- and there are many of them -- who buy into these suppositions might as well believe in the tooth fairy.

Here's why. Gold reached a record high of US$850 an ounce in January 1980. If since then the spot price of bullion kept pace with US inflation as measured by the consumer price index, gold would now be selling for US$2,119.84. Instead, it stood at US$732.05 in London trading yesterday, only about a third of what it should be if it were truly an effective inflation hedge.

History shows that since 1988, the correlation between bullion and US inflation expectations is just 36 percent, according to Goldman Sachs Group. That means the price of gold rises and falls with inflation expectations 36 percent of the time. The relationship between gold and US consumer price inflation is less, at only 23 percent. And the metal's correlation with US core inflation, which excludes food and energy costs, is even lower, at 7 percent.

"Gold is often described as an inflation hedge, but in fact there are few instances in the past 20 years when gold has moved in sync with either core or headline inflation," said James Gutman, a London-based commodity economist at Goldman Sachs International.

Thus, gold "should not be used as an inflation hedge," he said.

Investors seeking protection from inflation would have been better off in the US stock market. On Jan. 30, 1980, the Standard & Poor's 500 Index stood at 115.20. Adjusting the index to compensate for the increase in the CPI since then would put it at 287.30 today. Yet on Oct. 3, the S&P 500 closed at 1539.59, more than five times the inflation-break-even level.

As for political risk, the inflationary expectations associated with the Sept. 11 terrorist attacks on the US -- arguably the most dire threat to US security since the 1962 Cuban Missile Crisis, or even World War II -- had no lasting impact on the price of gold.

For instance, gold was selling at US$276.25 an ounce on Aug. 31, 2001, less than two weeks before the attacks; after rising to as high as US$295.10, bullion was back at US$274.25 on Oct. 23.

Whatever effect inflation has on gold is transmitted through the dollar's exchange rate. Since 1988, gold has moved in tandem with a basket of currencies consisting of the Australian and Canadian dollars, South African rand, euro, yen and Indian rupee 91 percent of the time, Goldman Sachs said. And dollar weakness is often associated with inflation.

Even so, there is little to explain movements in gold prices once the currency relationship is accounted for, Gutman said.

In any event, with the 1997 introduction of Treasury Inflation Protected Securities (TIPS) in the US and similar products in other countries, there's no reason to use gold as an inflation hedge. TIPS are US Treasury bonds whose principal increases at the same rate as the CPI. The interest payment is then calculated from the inflated principal and paid at maturity.

What's more, inflation isn't a problem currently, even though the Fed last month cut its fed funds rate by half a percentage point to 4.75 percent, and traders are betting there's a 70 percent chance it will fall to 4.50 percent later this month. US consumers expect a US inflation rate of 3.1 percent in a year, the Reuters/University of Michigan preliminary September index of consumer sentiment showed.

Still, the CPI fell to 2 percent year-over-year in August, down from 2.4 percent in July and 2.7 percent in June.

"It's far too early to expect higher inflation," said David Abramson, Montreal-based chief currency and commodity strategist at BCA Research.

Gold has been on a roll. It's up 15 percent so far this year, climbed to a 27-year high of US$747.90 an ounce on Oct. 1 and is on course to rally for the seventh consecutive year. Behind its rise has been the abundance of global liquidity and, more recently, the Fed's relaxed monetary policy and weaker dollar.

Bullion has also benefited from strong jewelry demand in emerging-market countries such as China and India; shrinking global mine production, especially in South Africa; reduced net central bank gold sales; and the growth of gold exchange-traded funds, which make it easy for individuals to invest in gold and which have US$17.7 billion in assets, Morgan Stanley said.

This shows that although gold may be a poor hedge, it isn't necessarily a lousy investment.

"It should be invested in for the right reasons," Gutman said.

Nonetheless, bullion has no direct link to economic growth as do other commodities, doesn't earn a return, offers limited hedging advantages and hasn't kept pace with inflation.
